Abstract: The invention relates to a method and apparatus for measuring at least one of the parameters flow rate, flow velocity, concentration and quantity of radon and/or radon daughters in the ground. The method is characterized by collecting gas arriving from the ground in a first chamber which is gas-permeable at the bottom thereof, at least the downwardly extending boundaries of the chamber being in contact with the ground, so that atmospheric gas is prevented from passing into the chamber. At least one detector which measures alpha-radiation from the decomposition of radon and radon daughters is placed in a second chamber communicating with the first chamber. Positioning of the second chamber and the detector is selected so that the detector can continuously be observed and utilized for the measuring operation. The gas is allowed to pass continuously. through the chambers over a given period of time, to expose the detector to the gas. Subsequent to this exposure, the measuring result registered on the detector is evaluated. The method can be modified for measuring radon departure from the surface of the ground, the gas-permeable first chamber being arranged over the surface of the ground to be analyzed. The detector is placed in a second chamber communicating with the first chamber. For the purpose of measuring the flow rate and velocity of radon passing through the ground there is provided a first chamber beneath the level of the ground, at a desired depth. This first chamber is connected with a gas-impermeable passage to a second chamber which can be readily reached from the level of the ground and which is sealed against penetration of atmospheric air. The detector is placed in the second chamber.

IPC: A61C8/00
Filed: 1990-10-19
Granted: 1997-03-11
Abstract: A system and method is provided for implanting tooth analogues in the jawbone resulting in aesthetically and functionally desirable gingival tissue contours after restoration.    The  system  permits  modification  and adaptation of the tooth analogue to meet  intraoral demands  in  a  manner  similar  to  that  used  in  the preparation and restoration  of natural teeth.   The system comprises a standard fixture and cover screw passed through opened gingival tissue and implanted in the jawbone.  After the ossointegration of the fixture, the gingiva is reopened, the cover screw removed and a healing cap having a predetermined contour, is attached to the fixture.   The reopened gingiva re-heals in a shape determined by the contour of the healing cap.  The healing cap is then removed and replaced by an abutment having an emergence profile matching that of the healing cap.  An immediate snug fit between the gingival tissues and the abutment is thereby provided at the time of connection of the abutment to the fixture.  A crown in removably attached to the abutment by a screw extending through the side of the crown into the abutment. An improved version of the healing cap is a healing cap created in two portions so that one portion around which gingiva tissue regrows remains in the patient and only a second upper portion is removed,  and an improved abutment which is engagable with the portion of the healing cap left in the patient is used for the abutment about which the crown is removably attached.
